' Be it known that I, VVILLARD D. LooK- wool), a citizen of the United States, residing at Schenectady, in the county of Schenectady, State of New York, have invented certain new and useful Improvements 1n Concrete-Buckets; and I dohereby declare the following to be a full, clear, andexact invention, such as Wlll endescription of the able others skilled in the art to which 1t appertainsto make and use the same.

This invention relates to hoistingbuckets of the dumping type and has especial reference to a bucket constructed for handling concrete andother cementitious material One'object of the, invention is to provide a bucket of such construction that the hinges will be kept free from concrete and the hinge portion of the dumping doors kept clean.

Another object of the invention is to so construct such a bucket that the concrete will have an unobstructed. path when thebucket is dumped.

- ance with this invention, the doors being.

A third object of the invention is to provide a novel construction of'bucket wherein the abutting edges of the doors will be automatically cleaned.

A fourth object of the invent-ion is to provide a novel bail arrangement for such a bucket of improved character.

With the above and other objects in view, the invention consists, in general, of a bucket. provided with bottom drop doors of novel construction together with a novel bail arrangement for supporting the bucket.

The invention further consists in certain improved arrangements of details and novel constructions of parts hereinafter fully de-.

scribed, illustrated drawings, claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and :Figure 1 is a side elevation of a bucket constructed in accordin the accompanying and specifically set forth in the shown in full lines as closed when the bucket is being hoisted and in dotted lines as closed when the bucket is set on car or the like. Fig. 2 is a similar view showing the bucket open. Fig.1? is an end elevation of the bucket with the doors open. Fig. 4 is a de tail in sed'tionshowing the hinge portion of the door and end wall.

, door plate is provided at that centric with the hinge pin 14 bucket and this body is preferably of the usual form with parallel sides and endsthatincline inward from topto bottom, Around the top and bottom of the bucket are the usual reinforcing bands 11.

Upon the end walls of the bucket are mounted angles 12 arranged in pairs and in spaced relation. These angles extend slightly below the bottom of the bucket as indicated at 13 and are there provided with suitable perforations to receive a hinge pin 14. In' the form here shown, two pairs of these angles are used but it is obvious that as many pairs may be used as are requ'; ed for the size of bucket used.

Doors15 are arranged to close the bottom of the bucket and these doors have their sides and meeting edges provided with stiffening angles 16. Upon each of these doors are mounted tee'irons 17 which are so positioned that the Web of the iron extends between the angles 12, and this web is provided with a suitable perforation to receive the pin 14 which passes through those angles. The part which is adjacent the end Wall of the bucket with a.

meeting edge which is arcuate in cross section as indicated at 18 and this edge is condoor is'swuiig open or shut the bottom edge of the end wall'of the bucket will scrape all concrete from thehin'ge edge, thus permitting the door to close without straining the hinge. In order to close these doors a bar 19 is provided on each and this bar passes through the side angles 16 and the tee'irons 17, projecting beyond the stiffening 16 on each side of the door. Attached. to the bucket near the upper edge thereof are guide clips 20 through which extends the legs of a bail 21. as at .22 and through these forkedends-pass pins 23. One of the doors 15 has'fpiv-oted thereto links 24 which have their upp'er'ends provided with a suitable perforation to receive the pins 23. The other door has 'pivoted thereto a pair of links 25 which have their upper ends slotted as at 26 to receive the pins 23. The length of the links 24 is slightly less than the length of the links 25. hen the bail 21 is pulled upward during the operation of hoisting, the doors 15 will The numeral 10 indicates the body of the The legs of the bail 21 are forked so that as the be held in the position indicated in full lines I in Fig. 1. When, however, the bucket is set down for filling or transportation, the doors assume the position shown in dotted lines in Fig. l. and the meeting edge of the door which is fully closed will be scraped clean by the eorrcspon ding edge of the door which is slightly open. This movement is permit ted by reason of the slotted connection 26 between the links and the bail.

For the purpose of limit the downward movement of the ball 21., this bail is provided with stop lugs 27 arranged to contact with the upper edge of the bucket.

Upon the upper part of the bail 21 is rigidly mounted a guide plate 28 through which passes a bar 29 having an eye 30 formed at the upper end thereof. The lower end of the 'bar 29 is rigidly attached to a fixed bail 31 which is rigidly mounted within the bucket, the bail 31 and the bail 21 both lyingin the same plane.

In using this bucket, the same is filled in the ordinary l'lltlllIlQl, the doors being held in i the position shown in Fig. 1 either by placing Fit tit)

the bucket on the ground or by supporting the bucket from the bail 21. IVhen it is desired to 'dump the bucket, the hoisting rope which. is connected to the eye 30 is held taut while the rope connected to the bail 21 is slacked ofi so that the bail 21 is permitted to drop along the bar 29 and the doors will then open. By reason of the bar 29 being rigidly connected to the bail 3'1 and supported at its upper end by the hoisting rope, the bail 21 will be guided therealong so that no lateral movement of the upper portion of the bail will take place.

There has thus been provided a simple and c'tlicient device of the character described and for the purpose specified. I

It is obvious that many minor changes may be made in the form and construct-i on of the invention without departing from the material principles thereof. It. is not, therefore. desired to confine the same to the exact form heroin shown and described, but it is wished to include all such as properly come within the scope of the appended claims.

.l-laving thus described the invention, what is claimed as new, is:
